Individuals 40 years of age and older who received their first dose of AstraZeneca and choose to have a second dose of AstraZeneca are eligible at least eight weeks after their first dose, with informed consent.

The National Advisory Committee on Immunization says an mRNA vaccine is preferred for a second dose due to emerging evidence, including the possibility of better immune response and the safety of mixing vaccine brands for first and second doses. For more information on options for those with a first dose of AstraZeneca, see our frequently asked questions.

Public Health can help you book at our clinics if you don't have any identification:

Second dose information

You don't have to book your earlier second dose at the same place you had your first dose (even if you already have a previous second appointment booked).

If you already had a second dose booked through the Provincial booking system, and choose to rebook your second dose for an earlier date, the booking system will automatically cancel the appointment on the later date. If you receive your second dose at an earlier date at a walk-in clinic, please cancel your previously booked appointment.

If your first dose was an mRNA vaccine (Moderna or Pfizer), your second dose should be at least 28 days after your first dose.

If your first dose was a viral vector vaccine (AstraZeneca), you're eligible for a second dose at least eight weeks after your first dose, with informed consent.

Third dose information

Ontario announced that the following individuals are eligible for a third dose of COVID-19 vaccine. Hospitals, through their clinics, are responsible to take the lead in vaccinating eligible individuals for third doses. In most cases, this means the hospital will provide eligible individuals with their third dose.

Health care providers that are administering the vaccine at their office may also provide third doses to their eligible patients.

In some cases, eligible individuals may be referred elsewhere for a third dose. The provincial booking system doesn't currently allow for third dose bookings.
